Transformers always reflect impedances from one winding to another by the square of the their turns ratio or, expressed as a formula: Zp/Zs = (Np/Ns)2 where Zp is primary impedance, Zs is secondary impedance, and Np/Ns is turns ratio (which is the same as the voltage ratio).

The step-up transformer increases the audio output signal voltage to 100V. Due to the Formula P (W) = V x A, when a voltage is increased the current decreases for a given power. The resistance would not effective for the low signal current. The signal will transmit perfectly.

Fig. 2: Turns Ratio Proving Relation Between Impendance and Turns in an Audio Transformer Where, Zp = Primary Impedance Zs = Secondary Impedance Np = No of turns in a primary Ns= no of turns in a secondary Thus, if output amplifier stage has an input impedance of 1800 W and loudspeaker impedance is 8W, a transformer is needed having turns ratio of

By using the above formula, we can calculate the turn number of windings required. It is proportional to the ratio of input and output impedances: n=Np/Ns=(Zp/Zs)1/2 where Np and Ns designate the primary and secondary turn numbers. n=(4096/4)1/2= 32; The equivalent transformer impedance can be then calculated (tube impedance is 5 kOhm and Zp is

As the turns ratio of the transformer is 10:1 the increase in apparent resistance (or impedance) is the square of the turns ratio. This relationship is described by the formula; ZP= ZS(NP/NS)2 Ensuring that the output stage of an amplifier is correctly matched to its load. 100V Line Transformer.
